如何用 tikz 繪製高振盪函數

Question

我嘗試繪製 sin(100x) 和類似的高頻 sinx 圖；但情節看起來不是那樣的。有人能幫我嗎。

\documentclass{article}

\usepackage{subcaption}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{adjustbox}

\begin{document}


\begin{figure}
        \centering
        \begin{subfigure}[b]{0.4\textwidth}
            \begin{tikzpicture}
                \begin{axis}[domain=0:1]
                \addplot {sin(10*deg(x))}; 
                \addplot {sin(25*deg(x))};
                \addplot {sin(50*deg(x))};
                \legend{$\sin(10x)$,$\sin(25x)$,$\sin(50x)$}
                \end{axis}
            \end{tikzpicture}
        \end{subfigure}
        \hfill
        \begin{subfigure}[b]{0.4\textwidth}
            \begin{tikzpicture}
                \begin{axis}[domain=0:1]
                \addplot {sin(100*deg(x))}; 
                \addplot {sin(150*deg(x))};
                \addplot {sin(200*deg(x))};
                \legend{$\sin(100x)$,$\sin(150x)$,$\sin(200x)$}
                \end{axis}
            \end{tikzpicture}
        \end{subfigure}
        \caption{lajsdfls}
\end{figure}
    
\end{document}

像這樣？

MWE 與下面建議的解決方案之間的主要差異在程式碼中標記為% <---：

\documentclass[margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}
    \begin{tikzpicture}
\begin{axis}[
    trig format=rad,    % <---
    domain=0:1,         % <---
    samples=501,        % <---
    no marks,           % <---
% 
    legend style={font=\footnotesize,
                  cells={anchor=west}}
    ]           
\addplot {sin(10*x};
\addplot {sin(25*x)};
\addplot {sin(50*x)};

\legend{$\sin(10x)$,$\sin(25x)$,$\sin(50x)$}
\end{axis}
    \end{tikzpicture}
\end{document}
